NAME 🖥️ getw 🖥️

input and output of words (ints)

LIBRARY

Standard C library (libc, -lc)

SYNOPSIS

#include <stdio.h>
int getw(FILE *stream);
int putw(int w, FILE *stream);

Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

getw(), putw():

    Since glibc 2.3.3:
        _XOPEN_SOURCE && ! (_POSIX_C_SOURCE >= 200112L)
            || /* glibc >= 2.19: */ _DEFAULT_SOURCE
            || /* glibc <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE
    Before glibc 2.3.3:
        _SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE

DESCRIPTION

getw() reads a word (that is, an int) from stream. It’s provided for compatibility with SVr4. We recommend you use fread(3) instead.

putw() writes the word w (that is, an int) to stream. It is provided for compatibility with SVr4, but we recommend you use fwrite(3) instead.

RETURN VALUE

Normally, getw() returns the word read, and putw() returns 0. On error, they return EOF.

ATTRIBUTES

For an explanation of the terms used in this section, see attributes(7).

HISTORY

SVr4, SUSv2.

BUGS

The value returned on error is also a legitimate data value. ferror(3) can be used to distinguish between the two cases.
